Aspects to Consider When Buying a Furnace Humidifier

Furnace humidifiers increase the moisture within the entire home. It is built as part of the HVAC system and is often mounted on the ventilation duct near to a furnace. These humidifiers run only when the furnace is in operation. Looking for a furnace humidifier is not difficult since it is available in many stores.

With a wide variety of types and brands of furnace humidifiers, choosing a good one can be overwhelming. To help you, here are the essential features that you should check in a furnace humidifier:

1. Type

Steams humidifiers, evaporative, and aerosol are the three basic types of furnace humidifiers. The steam humidifier works like a vaporizer similar to the one used for therapeutic purposes. It functions by heating the water up to the boiling temperature and filtering the steam into the air. Although it can be more expensive, it can expel a significant level of humidity.

The evaporative humidifier is made of a drum with mesh or foam pad cover. This drum turns and dips the pad into a pan of water. However, if the water becomes stagnant in the pan, it can cause the growth of bacteria and molds. A flow-through humidifier is a better variation because it doesn’t hold water.

The aerosol humidifier sprinkles a mist of water that evaporates into the air. It is rarely used because it requires regular maintenance to prevent the nozzle from clogging. Clogged vent causes the water to drip into the furnace that can damage the humidifier unit.

2. Coverage Area

The coverage area of a furnace humidifier depends on the size of the house. It is usually indicated in square feet. It should match the square footage of your home, eliminating the rooms that are not linked to the duct system. Determining the coverage area of a furnace humidifier should be easy because it is printed in the product’s specifications.

Installing a small house humidifier in an enormous 4,000-square foot house is not enough to humidify the air to a comfortable degree. Examples of house humidifiers are the bypass, drum, and flow-through humidifiers. They operate with your home’s cooling and heating system to diffuse moisture all over the house as the air is cooled or heated.

On the other hand, a furnace humidifier with large coverage area can be a waste of electricity and water. If you think that your home is too small that it doesn’t need to be entirely humidified or you plan to install it in one of the rooms, think of purchasing room humidifiers.

3. Maximum Out Per Day

The maximum out per day refers to the amount of water that can evaporate into the heated air within 24 hours when the humidifier is operating at full speed. The measure of maximum out per day is directly associated with the coverage area rating of the humidifier unit. However, some manufacturers have variations in the furnace humidifier ratings.

Generally, furnace humidifiers require 16 gallons of water per day or more for 3,000 to 4,000-square foot homes. This rating is plenty enough. When buying a humidifier, check for the maximum output capacity which is usually indicated in the unit’s specifications.

4. Weights and Dimensions

The weight and dimension are an essential consideration when buying a furnace humidifier. This is especially true if you are going to install it in a cramped room like a basement or attic. A humidifier with smaller dimensions would be more convenient for a tiny furnace room.

Also remember that once the unit is installed, you should not remove it or carry it around. An exception would be for occasional maintenance or repair.

5. Warranty

Furnace humidifiers can cost as low as $20 and as expensive as $250 and up. This is one of the house equipment that you want to purchase only once because of the cost, maintenance, and installation. A furnace humidifier with high quality is a significant investment.

It would be smart to have a good warranty from the manufacturer to secure your purchase. The guarantee is required so that you will have peace of mind. Many humidifier products come with a five-year warranty, but some come with a 10-year warranty which is a good deal.

6. Extra Features

Other features to consider when purchasing a furnace humidifier are the added functionalities. For example, some units have automatic power on/off function depending on the humidity and temperature. Usually, inexpensive units have manual control, while more advanced units come with digital control.

To reach the ideal humidity of your home, you need to identify its actual humidity levels first. This functionality may come in a separate device or as an extra feature in a furnace humidifier.

Some furnace humidifiers have integrated automatic humidistat or humidity control sensor. Other extra features are the Fahrenheit/Celsius conversion, UV germicidal light, indicator lights, maximum humidity level alert, backlights, and strong internal memories, among others.

The Verdict

You have just been presented five furnace humidifier reviews. All of them have a solid built and come with notable unique features that can match various needs and preferences for home humidification.
